' JOSEPH v. nonINsoN, oF CHEVY cHasn, MARYLAND. AUToMArlIe TRAIN-rien conimc'ron- Application led October 15,

To all whom it may concern:

'change between such' car and one not equipped with the automatic device.. The

'construction greatly expedites the renewal of defective hose andl provides a convenient,

slmple means for etfecting eilicient 4interchange .of cars during the'period of transif tion.

To this end my invention consists in the combinations, improvements and construe7 tions hereinafter'described, pointed out in' the appended claims, and illustrated in the accompanying drawings, in whiclir.-

Figure 1,- is a side"elevation yof my improvement. f/

Fig. 2, is a .view simi/lar to Fig. 1, showing my improvedcnieans .of connecting the hose 4of a car tofthe automatic connector, con nected tof'the interchange device .for-'eou pling af'car not equipped with the automatic connector to a car having it. Y

/Fign 3, is aside elevation of my improved interchange device or coupling D. Fig. 41, is a -side view of my improvedmeans for conncctingthehose of a car to the automatic connector. In this view some of the parts are shown in section. 1 f

Fig. 5,f`is-a view' similar to Fig. 4 but shows my improved meahsjfor connecting .f the hose of a car tothe connector, coupled terch to the head 23 of my impr' ved interchange device. .In this view' the atch for locking these members together is shown in theservic'e position. l ,A

Fig. 6, is anlend view of my improved inange coupling. In this 'yiew the head of the coupling is omitted, and

Fig.v 7, is an end' view of the member 15 of my improved means for connecting the hose of a car to the connector and -`to the head 23 of the interchange.dtwice.`

Y Referring to thedrawing'sf My improived l connector cad A is shown mounted upon-JIA a support B. which yieldably supports. the, head, allowing it to :novato thel various pofg Specification of Letters Patent..

. Patente sitions required in service. Any satisfactory form of such support. may, of course, bel used with the connector head and any sultablenform of connection for the support to the car may be employed, such -as a hanger Sto which' the base C of the support is connected as`by bolts 9.

My improvedV means for `connecting the hose of a carequippedwiththe automatic connector to the conduit 10 of lthesupport B and for effecting eiiicient interchange b etween a car so equipped and, one hiYing the present hand system comprises a male member 11 suitably connected to `the conduit 10 as by threads,

dially extending proJe'ctions or lugs.. 13 adapted to interlock or normally rest complementary lugs 14 of a female Vmember 15 carsried by the train pipe hose 16 of the car. y a

y and provided with va Hat cor'- rugated face 12 and oppositely disposed rabehind id female member'is provided witha circumferential seat-or groove 17 for 're- I a suitable gasket orsealing device ceivingl bottom of the seat being corrugated 18, theu Vas shown to give a better joint. VThe gasket 18 is U4 shaped in crosssection and hollowed out as at 18 to allow the Huid within the conduit 10'to expand thel gasket axially of the hose 16 into tight engagement with the seat 17 in the member 15 and the face 12 of the member` 11, which last member is o- Vsitioned in the conduit 10 so thatthe hose 16 must be twisted to. bring the lugs 14 into position to pass between the lugs 13 of the member 11. When .the 'twist of the hose is spent or let out, the lugs 14 rotate behind the lugs 13 inwhich position they are main- 16, insuring against accidental disconnection of the Vtamed by the torsional resistance of the hose parts. See particularly FigsJ: and

To ,couple the hose 16 into interchange communication with the hose of a car not equipped with the automatic connector, it is;

disconnected from the member 11 byrotatirigf it to the right orleft and shifting 1t axiallyI of such lmember 11 and is then connected to Hbc' a dummy or interchange coupling D in the same manner that it is connected to the member 11, after which connection to the hose 19 of the unequipped car is electedin the fashion now universally employed; that is. o say, the head 20 of'the coupling D is colnected with. a like head 21 in the end of. the hose 19. The interchan ge coupling'comprises said head? 20, a su itable shank4 22,

.made of any suitable mateiiaL and .a1 head, i

illustrates particularly the construction o ii' the male 'member 11 which is connected to the conduit viO'as by threads. I prefer to carry the coupling D separately of the automatic connector and use it interchangeably With a number of' connectors', though I ani aware that it may be otherwise carried if desired, such as connected permanently with the connector. j

By the foregoing construction I have produced a simple and eiiicient common means for connecting the hose of a'icar to an automatic connector or to all interchangedevice, in such Wise that the joint at the point of suchv connection is sealed, or the tightness thereofaug'niented, by the pressure of the fluid Within said hose and said joint, whereby eiiicient connection of said hose-to anantomatic connector o1' to the hose of a car not equipped with the automatic device, may be readily attained.

Having thus described my said 'invention,

' what I claim as n evvandv desire to secure by United States Letters Patent is 1. In anautomatic train pipe connector,

the combination Withv the coupling head. thereof and the train pipe hose of a car, of a fluid conduit extending from sai-.d head: laterally thereof', a member connected With sai-id conduit and 4provided With radially extending lugs arranged concentric with. the axis'y of the passage through said member and having also a face, av second member conneetedwith saidhose and provided with' a seat and' having also inwardly projecting the passage through said member and' adapted to., cooperate -With-` the 'lugs of said lfirst member to lock the membersvtogether, and

3. The combination -vvit coupling separate, ,of said hose, 'and means j "oiinector or said. int f 65, said means comprisiu v si lugs arranged concentric with the axis ofl with said hose and provided with projections adapted 'to cooperate with complementary projections on said connector and said interchange coupling.

'5. In an automatic train pipe connector, the combination ot a coupling head, acondnit leading from said'headand carrying Voppositelfy disposed projections, an interchange. coupling adapted to connect withA a similar'coupling Aof the hose of a 'ear not equipped with said automatic connector and having also oppositely ydisposed projections, a hose norm-ally, disconnected from said interchange coupling, a member mounted in said hose and' rovided with inwardly'extending projec ions adapted to4 interlock with the projections either of vsaid'cond-uit or said interchange coupling, vvherebj7- said hose is adapted tobe connected-interchangeably with said conduit and said interchange coupling, and a packing for sealing the Joint between said member and said inter. change coupling, said packing being extfldedltO tight engagement wi'th said member 'and said interchange coupling by the pressurev of the fluid i n said coupling.'

6. In an' automatic train pipe connection' the combination of a coupling head, -a' conduit leading from said head 'andcarryin-g oppositely disposed projections, an interchange coupling 'adapted to connect with a similar' coupling of the hose' of a carnet equipped with said automatic connector and ably with said conduit and said interchan e coupling, and a device forv locking said having also oppositely disposediprojectlons,
